The lower ends of the plates I6, Ilia of the standard are joined at oneside by a rivet or coupling pin which prevents a spreading of saidplates, and at the same time permits the swinging movement of the leverinto the space 36 between adjacent faces of the plates when in thecollapsed position shown in Fig. 4.

In the use of the tool, it will be understood that the part 28 of thelever may be raised and lowered in the post or standard ID to disposethe pivot pin 26 in either one of the offsets 23, 24 and 2 5, the samebeing shown in the offset 25 in the construction shown in Fig. 1. thehead 36 is placed beneath thehand grip- I3 of the sash l2 and downwardpressure is applied on the part 3| of the lever which will operate todisengage a binding or sticking sash l2. In this connection, it willalso be understood that the pin 26 may be disposed in either one of theapertures 2'! to increase or decrease the length of the protruding endof the lever part28 with respect to the standard, or as seen in Fig. 6of the drawing, a lever part 28a similar to the part 28 may have in itslower edge a series of recesses 31 to engage the pin 26' to provide thisadjustment without removing the pin 26 from the standard or body l6.

It will be understood that while I have illustrated the device as usedfor the purpose of. raising or freeing window sashes, the same may be.used for any other purpose as a jack or lifting tool, and while I haveshown certain details of construction for carrying my invention intoeifect,

and modifications of the construction herein shown and described may bemade within the scope of the appended claims without departing from thespirit of my invention or sacrificingits advantages.

Having fully described my invention," what I to secure by Letters 1. Adevice of the class described comprising a standard consisting ofparallel plates spaced apart ,to form an elongated recess therebetween,a rela -tively long lever disposed in the recess of said standard, meansfor pivotally supporting one end portion of the lever to said standardto dispose one short end of the lever outwardly of the standard, saidshort endhaving a transversely offset member, and said lever includingrelatively movable parts adapted to be collapsed to dispose the same insubstantially parallel relation with each other and to the longitudinalplane of the standard, and one part-of. said lever disposed within therecess of the standard when in collapsed position.

cluding pivotally coupled parts adapted to be folded into parallelrelation with respect to each other, one part being disposed within'thepost and the other part being oifset to clear the post to dispose saidparts of. the leversubstantially,

not in use.

3. A device of .the class described comprising a stock or body, arelatively long lever, means for pivotally supporting the lever inconnection with said body, said body comprising parallel sheet When sopositioned,

metal plates, means at the ends of said plates for coupling said platestogether to form a space therebetween opening through the front, back,and partially through the top and bottom of said body for reception andmovement of said lever, and means extending longitudinally of saidplates for reinforcing the same.

4. A device of. the class described comprising a stock or body, arelatively long lever, means for pivotally supporting the lever inconnection with said body, said body comprising parallel sheet metalplates, means at the ends of said plates for coupling said platestogether to form a space therebetween opening through the front, back,

and partially through the top and bottom of said body for reception andmovement of said lever, means extending longitudinally of said platesfor reinforcing the same, said lever comprising an elongated strip ofmetal, one end of which is curled to form the cylindrical head and thelever adjacent the head being twisted to dispose said headv transverselywith respect to the lever.

5. In a lift device of the class described, a standard fashioned from asingle strip of metal, each end portion of. the strip being of similarconstruction and comprising an elongated plate having side flanges andan elongated aperture having a plurality of offset sockets, the stripbeing folded centrally to dispose said plates in parallel andspaced'relation with respect to each other, and means at one lowercorner portion of said plates for coupling and spacing the same informing said standard with the aperture and offset sockets of saidplates disposed in common transverse alinement.

6. In a lift device of the class described, a standard fashioned from asingle strip of metal, each end portion of the strip being of similarconstruction and comprising an elongated plate having side flanges andan elongated aperture having a plurality of offset sockets, the stripbeing fold- .ed centrally to dispose said plates in parallel and spacedrelation with respect to each other, means at one lower corner portionof said plates for coupling and spacing the same in forming saidstandard, with the aperture and offset sockets of said plates disposedin common transverse alinement, the lower ends of said plates includingintegral flanges extending outwardly and laterally with respect to theplates to form supporting legs, and facings of cushioning materialarranged on the lower surfaces of said supporting legs.

7. In a lift device of the class described, a standard fashioned from asingle strip of metal, each ,end portion of the strip being of similarconstruction and comprising an elongated plate having side flanges andan elongated aperture havinga plurality of oifset sockets, the stripbeing folded centrally to dispose said plates in parallel and spacedrelation with respect to each other, means at one lower corner portionof said plates for coupling and spacing the same in forming saidstandard with the aperture and off- ,set sockets of said plates disposedin common transverse alinement, and the central portion of "the stripbeing cut out where folded to form at the upper end of the standard alarge opening extending through the top and one side of the standard.parallel to the longitudinal plane of the post when I '8. In a "liftdevice of the class described, a standard fashioned from a single stripof metal,

ing folded centrally to dispose said plates in parallel and spacedrelation with respect to'each other, means at one lower comer portion ofsaid plates for coupling and spacing the same in 'forming said standardwith the aperture and oilset sockets of said plates disposed in commontransverse alinement, the central portion of the strip being cut outwhere folded to form at the upper end of the standard a large openingextending through the top and one side of the standard, and an elongatedsheet metal lever having a pivot pin adapted to be arranged in theapertures and offset sockets of said plates in adjusting the leververtically in said standard, and the free end of the lever including acylindrical head 011'- set laterally with respect to said lever.

9. In a lift device of the class described, a standard fashioned from asingle strip of metal, each end portion of the strip being of similarconstruction and comprising an elongated plate having side flanges andan elongated aperture having a plurality of offset sockets, the stripbeing folded centrally to dispose said plates in parallel and spacedrelation with respect to each other, means at one lower corner portionof said plates for coupling and spacing the same in forming saidstandard with the aperture and offset sockets of said plates disposed incommon transverse alinement, the central portion of the strip being cutout where folded to form at the upper end of the standard a largeopening extending through the top and one side of the standard, anelongated sheet metal lever having a pivot pin adapted to be arranged inthe aperture and offset sockets of said plates in adjusting the leververtically in said standard, the free end of the lever including acylindrical head offset laterally with respect to said lever, and saidlever including a handle portion offset with respect to the lever properand pivoted thereto to dispose the handle portion in common transversealinement with the lever and both parts of the lever in parallelrelation to the standard when the parts are 20
